To honor the 20th anniversary of Princess Diana's death, several of Di's personal items have been displayed over the course of the year. Previously, some of Princess Di's most famous dresses were curated in an exhibition, and, most recently, she was honored with a new garden at Kensington Palace. Now, more personal items from the late Diana's private residences will be on display for visitors at Buckingham Palace.

A box of cassette tapes by Lionel Richie, Sir Elton John, and more, a childhood typewriter, and a school trunk are among the special pieces, most of which were chosen by Princess Diana's sons Prince William and Prince Harry, according to CNN. A desk that the princess often sat at in Kensington Palace will be the main focus, while family photographs of her sons and other small tokens will be arranged around it. The exhibition will also include gifts the princess received on her travels, including a silver Cartier calendar from former president Ronald Reagan and Nancy Reagan in 1985.

The selection is part of a larger exhibition, called "Royal Gifts," that displays items given to Queen Elizabeth II during her 65-year reign. "Royal Gifts" runs until October 1, 2017, and marks the annual summer opening of Buckingham Palace's doors to visitors. CNN reports that in 2016 more than half a million visitors passed through the royal residence.

Perhaps Prince William will take Prince George to see his grandmother's belongings—the exhibition opens on July 22nd, which coincidentally marks the young prince's fourth birthday.
